Comparison of robot-assisted laparoscopic radical prostatectomy via modified extraperitoneal approach and transvesical approach.
Article in BMC surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo compare the clinical outcomes of two different surgical approaches for treating localized prostate cancer: extraperitoneal robot-assisted radical prostatectomy (Ep-RARP) and transvesical robot-assisted radical prostatectomy (Tv-RARP).
methodsThis study collected and analyzed data from patients with localized prostate cancer who underwent robot-assisted radical prostatectomy (RARP) within the same surgical team between October 2018 and March 2024. The cohort included two groups: the Ep-RARP group (37 cases) and the Tv-RARP group (29 cases). The primary outcomes analyzed were postoperative drainage time, length of hospital stay, surgical margin status, postoperative complications, urinary continence, and erectile function.
resultsThe baseline characteristics of the two groups of patients were consistent (p > 0.05), making them comparable. The Ep-RARP group had a significantly shorter hospital stay (7 days [5.5-8] vs. 9 days [9-10], p < 0.001) and shorter drain retention time (7 days [6-8] vs. 8 days [7-10], p < 0.001). There were no significant differences in intraoperative blood loss, blood transfusion requirements, and surgical complications. The duration of catheterization was similar in both groups (7 days [7-8] vs. 7 days [7-8], p = 0.135), as well as the distribution of Gleason scores, pathological staging (T1, T2), and positive surgical margin rate (p > 0.05). No significant differences were found in immediate postoperative urinary control rates (Tv-RARP: 20 [68.97%] vs. Ep-RARP: 26 [70.27%], p = 0.909), 3-month urinary control rates (Tv-RARP: 27 [93.10%] vs. Ep-RARP: 35 [94.59%], p = 1.000), or 6-month urinary control rates (Tv-RARP: 29 [100%] vs. Ep-RARP: 37 [100.00%], p = 1.000). The biochemical recurrence rate at 6 months was also comparable (Ep-RARP: 1 [2.70%] vs. Tv-RARP: 1 [3.45%], p = 1.000). Postoperative erectile function recovery at 3 and 6 months was similar between the two groups (3 months: Ep-RARP: 14 [37.84%] vs. Tv-RARP: 12 [41.40%], p = 0.804; 6 months: Ep-RARP: 18 [48.64%] vs. Tv-RARP: 17 [58.62%], p = 0.464).
conclusionBoth extraperitoneal and transvesical robot-assisted radical prostatectomy are feasible approaches for localized prostate cancer, offering comparable oncologic control and functional outcomes. However, the extraperitoneal approach demonstrates advantages in terms of shorter surgery time, drain retention time, and hospital stay.
